GEAR-SHIPPING MECHANISM.

SPECIFICATION formingpart of Letters Patent No. 727,084, dated May 5,1903.

Application filed el'nne 9, 1902. Serial No. 110,7'71- (No model.)

To all whom, it may concern.-

Be it known that I, EDWARD wrBunenss, a citizen of the United States,residing at Mil- Waukee, in the county of Milwaukee and State 5 ofWisconsin, have invented certain new and useful Improvements inGear-Shippin g Mechanism, of which the following is a specification,reference being had to the accompanying drawings, forming a partthereof. My invention relates to improvements in gear-shippingmechanism, whereby a driven member of the mechanism is caused to engagewith driver or be disengaged therefrom;

and the objects of myimprovement are, first, r 5 to provide a positiveengagement of the parts with no possibility of their accidentallybecoming disengaged; second, 'to avoid all friction of parts whendisengaged, and, third, to provide a mechanism that may be clutched orunclutched whether the parts be idle or in motion. I attain theseobjects by the mech-. anism illustrated in the accompanying drawings, inwhich Figure 1 is a plan view of a part of my invention. Fig. 2 is asection on line AB, Fig.

1. Fig. 3 is a plan view of the shipping-lever and swivel-piece. Fig. 4is a detail view of one of the shipper-hooks. Fig. 5 is a detail view ofthe cross-head and swivel and the 0 shipper-hooks. Fig. 6 is a detailview of the shipper-ring, and Fig. 7 is a detail view of theclutch-ring.

Similar numerals refer to similar parts throughout the several views.

3 5 1 is the main drive-wheel of a harvester;

2 is the main gear-wheel, that is journaled on the hub of wheel 1 andclutches therewith. Anannularchannel surroundsthehub of the wheel 1 atits inner end, and radial 4o ratchet-teeth are formed on the verticalflange of the channel, as, shown by dotted lines in Figs. 1 and 2.Surrounding the hub of the gear-wheel-2 is an annular ring 3, adapted toenter the channel in wheel 1. A clutch-ring 4 On the inner face of theclutch-ring 4: are radial ratchet-teeth adapted to engage with the teethon wheel 1. On the periphery of the clutch-ring A are longitudinal slots5, that engage with internal 5o longitudinal'ribs 6 on the annular ring3.

springs 11, that surround the connecting-rods 6o 10. The springs actingbetween the clutchring 4 and the outer wall of the enlarged portions ofthe holes in the hub of wheel 2' yieldingly hold the clutch-ring 1 inengagement with the clutch-teeth on the hub of wheel 1.

12 is a hub on the carrying-arm 13, and the axle of the main wheel issecured therein.

14 is a cross-head extending across the outer end of the hub 12, and 15is a swivel piece "pivoted in said cross-head. 7o

16 represents hooked rods secured in the ends of the cross-head andpassing through holes in the hub 12 and have their hooked ends engagingwith the annular groove Sin the shippingring 7. The hooks on these rodsare formed, as shown in Fig. A, broad enough to secure them from turningout of the groove 8 should they be loose in the cross-head 14.

17 is the operating-rod, formed with a crank at its outer end and at itsinner end given a double bend, forming a central crank 18 to act against.the end of the hub 12. The rod 17 is placed between the two forks onthe ends of the swivel-piece 15, and the ends are bent partially aroundthe rod to secure it therein, leaving the crank portion 18 central withthe pivot of the swivel-piece 15, as'shown in Fig. 3. A support for theouter end of the rod 17 may be attached at any convenient point on theframe of the machine.

The operation of the device is as follows: The clutch-ring at being heldin engagement with the ratchet-teeth on the hub of the main wheel 1 bythe force of the springs 11 and also engaging with the wheel 2 by meansof the 5 longitudinal grooves 5 engaging with the teeth 6 of said wheel2, the two wheels are connected in a manner that will positively producesimultaneous movement of the two when moving in one direction, and theclutch-ring 4 I00 will move away from the engagement with the teeth inthe main-Wheel hub when the said wheel is moving in the other direction.The movable clutch ring 4 being held by the clutch-wheel 2, they willboth be stationary when the ring is disengaged from the teeth in themain wheel, and there will be no friction or wear of any of the variousparts of the mechanism.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a clutch, the combination of a driving member having radialratchet-teeth concentric with the axis thereof, a driven member, aclutch-ring engaging rotatively with the driven member, and movablelongitudinally in relation to its hub, said clutch-ring having radialratchet-teeth adapted to engage with the teeth of the driving member,springs seated in cavities in the hub of the driven member, and actingto hold the clutch-ring in engagement with the driving member, ashipping-ring movable longitudinally on the outer end of the hub of thedriven member, connections between said ring and the clutch-ring thatmove rotatively therewith, and non-rotative mechanism connected with thesaid shipping-ring for the purpose of moving it longitudinally againstthe action of the springs.

2. In a clutch mechanism the combination of a driving member havingradial ratchetteeth concentric with the axis thereof, a driven member, aclutch-ring engaging rotatively with the driven member, and movablelongitudinally, in relation to its hub, said clutchring having radialratchet-teeth adapted to engage with the teeth of the driving member,springs seated in cavities in the hub of the driven member, and actingto hold the clutchring in engagement with the driving member, ashipping-ring movable longitudinally on the outer end of the hub of thedriven member, and provided with an annular groove, an axlesupportingarm, connecting-rods with hooked ends seated in said annular groove, andguideways for the rods in the hub of the supporting-arm, a cross-headconnecting the outer ends of said rods, an operating crank-rod journaledin a saddle-piece pivoted on the cross-head, said crank-rod operatingbetween the crosshead and the end of the hub, of the axle supportingarm, substantially as described.
